摘　　要：为筛选防治柑橘沙皮病的高效低毒药剂,连续两年进行了新型复配药剂50%克菌丹·啶氧菌酯水分散粒剂防治柑橘沙皮病的田间药效试验,对该药剂防治柑橘沙皮病的效果及安全性进行了评价。两年的试验结果表明:50%克菌丹·啶氧菌酯水分散粒剂有效成分用量625 mg/kg对柑橘沙皮病具有较好的防治效果,2018年药剂处理两次后对柑橘叶片和果实沙皮病的防治效果分别为78.46%和76.84%,2019年药剂处理两次后对柑橘叶片和果实沙皮病的防治效果分别为78.79%和75.59%,显著优于对照药剂80%克菌丹水分散粒剂800 mg/kg的处理,优于对照药剂22.5%啶氧菌酯悬浮剂150 mg/kg的处理。50%克菌丹·啶氧菌酯水分散粒剂对柑橘安全,值得应用于柑橘沙皮病防治的示范与推广。To screen the high-efficacy and low-toxicity fungicide for controlling Diaporthe citri,a two-year consecutive field experiment was conducted to evaluate the efficacy and safety of captan·picoxystrobin 50% WG against D.citri.The results showed that captan·picoxystrobin 50% WG at 625 mg/kg had a good control effect against D.citri on citrus leaves and fruits,the control efficacy of fungicide treatment twice in 2018 reached 78.46% and 76.84%,78.79% and 75.59% in 2019,respectively,which was significantly superior than that of captan 80% WG at 800 mg/kg,and better than that of picoxystrobin 22.5% SC at 150 mg/kg.Captan·picoxystrobin 50% WG is safe for citrus,which is worthy of demonstration and promotion D.citri control.
